Objective: To observe the effect of peptisorb on the result of intestinal preparation,the change of correlated nutritional index,the fuction of intestine and the immune function after operation in perioperative colorectal cancer patients.Methods: Sixty patients were randomly allocated into two groups. The trial group (n=30) received peptisorb 3days before and 7days after operation. Control group (n=30) received coloclysis treatment.The the level of Alb, globulin,the number of IgG, IgA,IgM, CD3+,CD4+/ CD8+ ,the station of intestinal mucosa and intestine cleaning during operation, nutritional state after operation, immune function, infcetious complications, length of stay were detected.Results: There were no significant difference in the station of intestinal mucosa and intestine cleaning. The index of nutritional and immune in two groups were descend, but the trail group was better(P＜0.01). The number of IgG,IgA, IgM, CD3+ in the trail group were significantly higher than the control group(P＜0.01),the rate of postoperative infectious complications in the trail group was lower than the control group.The trail group aslo showed shorter average length of stay after surgery than the control(P＜0.01).Conclusion: The peptisorb can ameliorate the host immune function and improve clinical outcome,which is a good nutrition support pathway to perioperative colorectal cance patinets.

Objective:To observe the efficacy of Chuankezhi injection combined with budesonide and formoterol fumarate powder for inhalation in the treatment of chronic obstructive pulmonary disease ( COPD) . Methods:Totally 120 patients with COPD were ran-domly divided into two groups:the observation group inhaled budesonide and formoterol fumarate powder for inhalation combined with intramuscular injection of Chuankezhi injection, and the control group inhaled budesonide and formoterol fumarate powder for inhala-tion. The treatment course was 28 days. The pulmonary function indices [ FEV1% expected value, FEV1 /FVC, 6 min walking dis-tance (6MWD)], the times of acute exacerbation and the adverse drug reactions during the treatment were observed and compared be-tween the two groups. Results:After the treatment, the lung function and 6MWD were improved in the two groups, and the improve-ment of FEV1% expected value in the treatment group was more obvious than that in the control group [(59. 7+12. 1)% vs (49. 8+11. 3)%, P<0. 05]. The number of patients with at least once of acute exacerbation was significantly reduced in the treatment group when compared with that in the control group (35% vs 62%, P<0. 01). The incidence of adverse drug reactions in the two groups showed no significant difference. Conclusion:Chuankezhi injection combined with budesonide and formoterol fumarate powder for in-halation can notably improve the lung function in the patients with COPD and reduce the times of acute exacerbation without effect on the incidence of adverse drug reactions.

Objective: To study the quality standard of Fangtuoshengfaling Lotion (Radix et Rhizoma Rhei, Radix Sophorae Flavescentis, Radix Polygoni Multiflori, Radix Angelicae Sinensis, Radix Astragali seu Hedysarion, etc.). Methods: Radix et Rhizoma Rhei, Radix Sophorae Flavescentis were identified by TLC. The content of 2,3,5,4′ tetrahydroxystibene 2 O ? D glucoside in Radix Polygoni Multiflori of lotion was assayed by HPLC. Results: The linearity of 2,3,5,4′ tetrahydroxystibene 2 O ? D glucoside was found in the range from 0.36～1.84ng. The average recovery was 96.866% and RSD =0.898%( n =5). Conclusion: The method was found to be simple, accurate and with a good reproducibility and may be used for the quality control of the Lotion.

Pituitary tumors, originated from homoral adenohypophyseal cells, are very common in intracranial neoplasms. They are characterized by a wide range of biological behavioral related to hormoral and proliferative activities. Previous pituitary adenoma studies mainly devoted to histological and ultrastructural classification with immunohistochemical techniques. Molecular biology allowed new approaches, especially concerning the pathogenesis and progression. This article reviews the progress of these researches regarding chromosomes, oncogenes, antioncogenes, transgenic animal models and genetic therapy.

Objective To review the recent studies about sentinel lymph node biopsy in breast cancer. Methods The literatures in recent years on the history, concept, technique and clinical application of sentinel lymph node biopsy were reviewed and summarized.Results There was no unified method for sentinel lymph node biopsy. There was a wide range of detection rate and false negative rate.Conclusion Prospective multi center random clinical trials will help to evaluate the clinical application of sentinel lymph node biopsy.

Objectives: To observe the clinical effects of nutritional support with protein diet in patients with moderate and severe burns. Methods: 50 cases were randomly divided into treatment group(25 cases) and control group(25 cases). The control group was treated with routine and nutritional support. The treatment group was given additionally with protein diet (80g/d,consisting of Gln 4g and protein 66g). Either oral admistration or tube feeling was chosen according to patient condition. The treatment lasted 21 days. Results: There was no significant difference between the two groups on the levels of Alb、PA、TF and TLC before the management. The level of Alb in the treatment group was obviously changed after the management. The levels of PA、 TF and TLC in the treatment group were increased significantly and had significant differences between the two groups(P

A high performance liquid chromatographic method with hypersil C_(18) column, 0.020 mol/L potassium dihydrogen phosphate solution(which contains 0.25% triethylamine, pH 5.1)-methanol(20∶ 80, V/V) as mobile phase and fluorescence detection with 280 nm as excitation wavelength and 320 nm as emission wavelength has been developed for the determination of terbutaline sulfate and propranolol hydrochloride in Erythrocyte suspensions. Erythrocyte surface receptor oscillating reacted 1 h with terbutaline in 37 ℃ water bath. Free terbutaline and propranolol were separated from the membrane receptor-binding complex through 1500 r/min centrifugal in 5 min. The linear range was 0.010-3.000 mg/L in Alsever's solutions and the correlation coefficients were 0.9999 and 0.9998. The relative standard deviations(RSDs) of terbutaline and propranolol were 0.8% and 1.2%, respectively. The limits of detection(LODs) of both were 1.00 and 3.00 mg/L. This simple, safety and sensitive method was suitable for the determination of terbutaline and propranolol in erythrocyte suspensions and for the study of receptor-ligand binding.

Sulfotransferase (SULT) enzymes play important roles in the biosynthesis of estrogen.These enzymes catalyze the sulfation of estrogens to form biologically inactive molecules. Several studies have shown that Arg213His polymorphism in SULT1A1 gene may be a risk factor for breast cancer. In addition, a low mRNA expression of SULT has been significantly associated with reduced recurrence and improved overall survival in patients with estrogen receptor (ER)-positive tumors. Furthermore, SULT may be a crucial factor in the response to tamoxifen treatment. As an important part of estrogen synthetic pathways, SULTs are closely re lated to breast cancer.
